Carbon fiber, fiber glass, composite materials, aluminum, and ceramics. http://forum.shrapnelgames.com/images/smilies/happy.gif Stronger, lighter, cheaper.

You've obviously never worked in customer service or tech support. You can't expect basic literacy from the average American consumer, or a grasp of logic, or any real semblance of intelligent thought.

Or maybe I'm just bitter... but I suspect I'm right.

I wasn't saying it was the heat, just that the cooling heat sinks you put into the block weaken the structure. The materials fine, but the structure is weakened by lots of holes in it. Plastics (normally) having piss poor thermal conduction you'd need alot of water content to get the cooling.

It's true I haven't looked at US cars for oh... ever. Me not living there and all. http://forum.shrapnelgames.com/images/smilies/laugh.gif

Most of the cars I see around here are metal bodied. Oh yeah plastic bumpers or whatever, but mainly metal bodies. Could be I'm just spectacularly unfortunate in all the new cars I see.

Re: Support That Is Based Outside Of USA
 

My truck (a 1995 Ford F-150) has metal bumpers, body, everything. But as far as I know, cars are being made of plastic more and more, as are the newer trucks.

Personally, I'd much rather be driving some 1970's-1980's car than a newer car. Why? The metal content. Sure, the plastic car and the metallic car may have similar strengths, etc. But everyone's failed to take into account a very important aspect; inertia. In a heavier vehicle, you will stand a much better chance of survival in the event of a collision with another vehicle, simply due to inertia.

It's pretty simple, the more complex the form of the car, the greater the chance of it being made from plastic or composites. Metal is very hard to form into some of the shapes and contours that are required on some of the new cars. Even with hydro-forming process the cost of molding is cheaper, so far.

Its the same with Asian cars as well. At least, all of the ones imported here in the US...

You should try the Red Green Cement Car. Really *really* bad gas milage, but if you're ever in an accident, you win. http://forum.shrapnelgames.com/images/smilies/happy.gif

Heh. The whole reasoning goes along the lines of "we don't care about our users", so their unability of getting through the flow sheet would not affect it. It was a "one step further" reasoning, so it does not exactly reflect my own views, opinions...

With all the science people on these boards, nobody's called bull**** on this yet? The weight of the vehicle does NOT increase the safety. If anything, extra weight makes car more dangerous.

You should recall from Newtonian physics, that inertia is the tendancy of mass to remain at it's current velocity (or speed and heading, if you prefer). When the vehicle is moving, the inertia causes it to keep moving at its current speed until outside forces slow it down. In a wreck, this outside force is applied during a fraction of a second. So, the equation for kinetic energy, E=(0.5)*m*(v^2), says that a vehicle that is twice as heavy will have to withstand twice as much energy on impact. With older cars, the extra weight does not add to the structure of the vehicle overall, and simply adds on to the stress the frame needs to deal with to protect the occupants of the vehicle.

Plastic bumpers, you say? They spread out the time of impact, as the bumper crumples up, absorbing a good percentage of the impact energy. With a metal bumper, there isn't really that much crumpling; it just turns into a metal bar that rams into the frame. The frame of the car would probably deform a metal bumper just as much as the impacted object would in a major crash.

For another way to look at it, think of egg drop contests. You go up to the roof of a moderately tall building (say, between two and four stories), and see what kind of vehicles will allow an egg dropped from that height to not crack. People come up with all sorts of schemes to protect the egg, and most involve either some kind of parachute (reduced speed of impact) or some kind of larger hard shell. But the killer in impact situations is all of the energy is dispersed in a short time period. The trick is to get the decelleration to take as long as possible. The impact can be half the speed of what it would have been without a parachute, and the outer structure could take a lot of energy, but the egg would still break if the decelleration time is 0.001 seconds. But spread out the time to 0.1 seconds, and the egg is intact. That is the route to go for safety.
